Step 1: Plan and Measure

  • Begin by carefully assessing your deck layout and considering where the railing will be installed.
  • Think about factors such as entrances, stairways, and areas where the railing is necessary for safety.
  • Visualize how the railing will complement the overall design of your deck and property.
  • Using a measuring tape, determine the total length of the area where you plan to install the vinyl railing.
  • Measure the linear distance along the edges of the deck where the railing will be attached.
  • This measurement will help you determine the number of railing sections needed to cover the entire space.
  • Be sure to account for corners, turns, and any gaps between sections.
  • Vinyl railings provide essential safety and support, so it’s crucial to mark the desired height for your railing on the deck posts.
  • The standard railing height is typically around 36 inches, measured from the deck floor to the top of the railing.
  • Some regions might have specific rules for residential decks, depending on factors like the deck’s height from the ground and its location.
  • With the railing height in mind, use a pencil or marker to make clear and accurate marks on the deck posts where the top of the railing will be positioned.
  • This ensures that all posts are consistent in height, resulting in a uniform and visually appealing installation.

Required Tools

  • Measuring tape
  • Pencil or marker
  • Level
  • Safety glasses

Step 2: Install Posts

  • Opt for strong and durable posts made of either wood or metal.
  • Wood posts offer a classic look, while metal posts provide a modern touch.
  • Choose options that are designed to withstand outdoor elements and can support the weight of the railing.
  • Determine the posts’ location based on your earlier planning and measurements.
  • Place the posts at the corners of your deck or at strategic intervals along straight sections.
  • Make sure they align with your intended railing layout.
  • Attach post mounts or brackets to the deck surface where the posts will be secured.
  • These mounts act as the connection point between the posts and the deck, providing stability and preventing wobbling.
  • Use appropriate anchors and screws that are designed for your specific deck material (wood, concrete, etc.).
  • Before securing the posts, ensure they are perfectly level.
  • Use a carpenter’s level to confirm that each post is vertically and horizontally plumb.
  • This step is crucial to maintaining the overall stability and visual appeal of your railing.
  • Once the posts are level, use the appropriate screws or fasteners to secure the post mounts to the deck surface.
  • Make sure the posts are tightly anchored and won’t shift or move over time.
  • The level and secure installation of the posts lay the groundwork for a solid and reliable vinyl railing system.

Required Tools

  • Sturdy posts (wood or metal)
  • Post mounts or brackets
  • Anchors and screws
  • Carpenter’s level

Step 3: Attach the Bottom Rail

  • Gently slide the bottom rail into the brackets on the posts.
  • The brackets are designed to hold the rail in place while providing stability.
  • Make sure the rail is centered and aligned with the posts.
  • Use a level to confirm that the bottom rail is perfectly straight.
  • This step is essential as it ensures that your entire railing system will look professional and polished.
  • Once the bottom rail is straight and aligned, it’s time to secure it to the posts.
  • Use the screws or fasteners provided in your railing kit to attach the bottom rail to the brackets.
  • Make sure to follow the manufacturer’s instructions for the type and placement of the screws.
  • Once you’ve attached the bottom rail, gently shake it to test for any wobbling or instability.
  • If the rail feels loose, double-check the screws and connections.
  • Before moving on to the next steps, take a final look at the alignment of the bottom rail.
  • Confirm that it’s level, straight, and securely attached to the posts.

Required Tools

  • Bottom rail
  • Brackets
  • Screws or fasteners

Step 4: Install Balusters

  • Carefully insert the balusters into the pre-drilled holes on the bottom rail.
  • The holes are designed to securely hold the balusters in place, ensuring they won’t move or shift over time.
  • Depending on your railing kit, you might need to slide the other end of the balusters into the top rail.
  • Some kits are designed this way to ensure a snug fit and consistent spacing between the balusters.
  • If required, gently slide the balusters into the corresponding holes on the top rail.
  • As you install the balusters, pay close attention to their spacing.
  • Use a measuring tape or spacer tool to ensure that the gaps between each baluster are consistent and visually pleasing.
  • Use a level to make sure that each baluster is installed vertically and level.
  • This step is essential for both safety and appearance.
  • Proper aligned Balusters prevent gaps that might compromise the safety of the railing.
  • Occasionally, you might encounter slight variations in the placement or alignment of balusters.
  • Take your time to ensure that each baluster is securely in place, spaced evenly, and aligned correctly.
  • After installing a balusters section, step back and assess the overall look.
  • Confirm that the balusters are level, evenly spaced, and visually appealing.

  • As you slide the top rail into position, use a level to ensure that it’s perfectly level and properly aligned with the bottom rail.
  • This step is crucial for both safety and aesthetics.
  • Once the top rail is level and aligned, it’s time to secure it to the balusters.
  • Use the screws or other fasteners provided in your railing kit to attach the top rail to the balusters.
  • After attaching the top rail, give it a gentle shake to ensure that it’s securely fastened to the balusters.
  • A stable top rail contributes to the overall integrity of the railing system.

Is vinyl railing cheaper than wood?

Wood usually costs less than vinyl.

However, vinyl becomes a better value when you consider the long term.

Vinyl doesn’t need maintenance and comes with a lifetime warranty, making it a smart choice.

How tall is a deck railing?

A deck railing should be at least 36 inches tall.

This measurement is taken from the top edge of the top rail down to the deck surface.

This standard height is common across most of the United States for residential decks, with a few states having different rules.

What is the spacing for deck railings?

The International Building Code (IBC) suggests that manufactured deck railing posts should be spaced at most 8 feet apart.

If they are spaced farther apart, it becomes challenging to meet safety standards, especially considering they need to support up to 200 lbs.
